Hi all, I'm having an issue with Sahara accessing its instances. This
is over private IP, not public/floating. I have use_floating_ips =
false and use_namespaces = true in sahara.conf. My setup also uses
Neutron, so use_neutron = true as well.
Here is an excerpt from the logs:
DEBUG sahara.utils.ssh_remote
[req-ad9e16b1-176b-4283-92ea-e2032928e3a0 ] [instance:
f2145fd1-fa9e-4d45-9d61-653bb6d6dd6d, cluster:

192.168.201.23, reason SSHException: Error reading SSH protocol banner
We would think this to be a networking issue, right? (Or maybe an SSH
issue...) However, when I perform the SSH command manually, I can
connect to my instances:
ip netns exec qdhcp-433d83c0-1f7f-4fb7-b4a1-995b47344ac4 ssh -i
/path/to/private/key ubuntu@192.168.201.23
The above command executes successfully and SSH connects.
Any help is greatly appreciated.
Thanks,
Jeremy Freudberg
